iPhone 7 (Rumor)
Available with the same 4.7 and 5.5-inch Retina displays, the iPhone 6s and iPhone 6s Plus have the same exterior design as the iPhone 6 and 6 Plus, but much of the hardware inside, from the camera to the processor, is new and improved. Core technologies like the touchscreen and the vibration engine have been updated, and the devices are even constructed from an entirely new material.
The iPhone 6s and 6s Plus are made from a 7000 Series aluminum alloy, which is stronger and more durable than the 6000 series used in the previous-generation iPhones. Apple's also updated the devices with stronger glass, made using a dual ion exchange process. One of the biggest changes is the introduction of a new aluminum finish in Rose Gold, which accompanies the traditional Silver, Space Gray, and Gold color options.
A second-generation Touch ID module makes fingerprint detection twice as fast, and the 64-bit A9 processor in the two devices is 70 percent faster at CPU tasks and 90 percent faster at GPU tasks than the A8 processor in the iPhone 6 and 6 Plus. A built-in M9 motion coprocessor enables new features, such as always-on "Hey Siri" functionality.
With the iPhone 6s and 6s Plus, Multi-Touch has been expanded to encompass a third dimension through a 3D Touch feature, and Apple is calling this "the future of Multi-Touch." In addition to recognizing a tap, sensors in the iPhones can also recognize pressure, enabling a range of new shortcut gestures Apple's calling the "Peek" and "Pop." A new Taptic Engine provides tactile feedback whenever the pressure-based gestures are used.
Most of Apple's "S" year upgrades include camera improvements, and the iPhone 6s and 6s Plus are no exception. Both devices have a 12-megapixel camera with some internal improvements to preserve color accuracy and speed up autofocus. The iPhone 6s Plus has Optical Image Stabilization, while the iPhone 6s does not.
With the improved camera, 4K video at 30 FPS is supported, and the iPhones can capture 63 megapixel panoramas. There's a 5-megapixel front-facing FaceTime camera with a True Tone Retina Flash feature that lights up the display of the iPhone just before a photo is captured.
The most novel camera-based feature available for the iPhone 6s and the iPhone 6s Plus is Live Photos, a feature that captures 1.5 seconds of movement before and after a photo is taken to display short animations and sound when a is used on an image. Live Photos is designed to add a sense of vitality and life to still photos.
There also appears to be a larger hole for the camera, which may or may not protrude slightly. Some iPhone 7 rumors have suggested the camera will not protrude at all, but others disagree. It appears that if there is a protrusion, it will be less pronounced than the camera bump on the iPhone 6s.
Images depicting what could potentially be the dual-lens camera component for the iPhone 7 Plus surfaced from multiple sources in the early months of 2016. The part has an "821" number on it, which has been associated with Apple in the past, suggesting it could be a legitimate component.
